I'm mostly a guitarist but like to dabble in bass at home. I've used a Roland Cube 100 with a Yamaha BB414 for years but lately I've been thinking of upgrading the amp. Don't take me wrong, it sounds fine but I keep thinking could I get better tones out of something else. What would you recommend if I want better sound than I have now? Preferably either a combo or a compact head + cab setup. I do have an Axe-Fx 2 but no suitable speakers for bass so that might be one option as well even though bass amp models are pretty poorly represented in the unit.
